Impossible Nail in Wooden Block
This is my take on a classic puzzling object that woodworkers have been making for years. If you’ve never seen the impossible nail-through-block-of-wood trick, check out Steve Ramsey’s great video here.
My version and approach is very different than Steve’s, however.
The nail is solid and has not been bent, cut, glued, or modified in any way. It slides back and forth within the block of wood, and the total length of the nail is longer than 2x the diameter of each hole.
The wood has not been boiled and squished or bent, as some people may suggest.
I made this because I love little objects that seem to defy physics and logic. They intrigue people and encourage them to think and reason, and I find it very interesting to observe how people respond when confronted with things like this.
If you’re interested in making something similar, read on. Thanks for taking a look.
Step 1: Materials
I used a piece of hardwood and a large 60d nail (which is 6 inches long). A smaller piece of scrap wood (like a piece of a 2×4) and a smaller nail (like a 20d nail) could be used just as easily.
You could use a large variety of tools to reach the same result I did, depending on what you have access to.
Here are the tools I used (links are to specific models I own and happily recommend):
